Wind vane steering
Prior to entering WIND mode the AP20 system should be
operating in AUTO, with valid input from the selected wind
transducer. The WIND mode is an alternative function to the
NAV mode and it is only available if the system has been set up
for SAIL-boat in the Installation Menu, and NAV/WIND source
is set to WIND under the USER SETUP menu. (Refer to page
31).
WIND function can only operate when reaching as it is
necessary to have a stable apparent wind. The sails should be
trimmed so that the autopilot easily can steer the boat in AUTO
mode and the wind transducer must give a stable signal.
Enter the WIND mode by pressing the NAV/SETUP button.
The pilot will read the apparent wind angle at the moment the
WIND function is selected and enter it as the set apparent wind
angle. From that point the pilot will change the course to
maintain this apparent wind angle as the wind direction may
change.
Note !
If the cumulative shift of the apparent wind exceeds 15° from the
value at the time the WIND mode was selected, a WIND SHIFT
alarm will sound.
The display will show the set apparent wind angle. Adjustments
to this set angle can be done by using PORT or STBD button or
the rotary course knob.
The display is also presenting current heading and rudder angle.
Dodging while in the WIND mode is very similar to dodging
while in the AUTO or NAV modes. Refer to DODGE mode
operation in the AUTO mode section on page 24.
